AIRSHIP Filed April 1l, 1929 3 Sheets-Sheet 5 Inventor Geo rye K1N/'56h /5 h/Imaam Attorney Patented Dec. 3, 1929 UNITED STATES PATENT OFFICE AIRSHIP Application led April 11,

The present invention relates to airships and has for its prime object to provide a structure of this nature simulating the shape and formation of a bird with flapping wings y; to propel the airship and to assist in causing the same to ascend in the air.

Another very important object of the invention resides in the provision of an airship of this nature having a hollow body filled with lighter than air gas and flapping wings with feathering blades therein and a pivoted tail to control the ascent and descent of the machine.

A still further very important object of 115 the invention resides in the provision of an airship of this nature which is simple in its arrangement of parts, and thorough efficient and reliable in use and operation,

With the above and numerous other objects in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more specifically described and claimed.

In the drawings: Figure 1 is a top plan View of the airship embodying the features of my invention,

Figure 2 is a vertical transverse section 320 therethrough,

Figure 3 is an enlarged detail sectional plan view of one of the blades.

Figure 4 is a sectional View therethrough taken substantially on the line 4-4 of Figure 3,

Figure 5 is a detail sectional elevation of one of the clutches between the engine shaft and one of the cranks,

Figure 6 is a sectional View through one of the wings showing a series of the blades,

Figure 7 is a side elevation of the airship,

Figure 8 is a vertical transverse section taken substantially on the line 8 8 of Figure 7.

Referring to the drawing in detail it will be seen that the letter A denotes a body with wings B hingedly mounted thereon to flap up and down and letter C denotes a tail hing edly mounted at the rear of the body A to swing up and down. The body A comprises cally and then when power is needed the i 1929. Serial No. 354,419.

a framework 5` with covering 6 thereover to form a gas bag and is shaped to simulate the body of a bird.

A cradle 7 depends from the body and supports an engine 8 with the power shaft 9 extending laterally from bothv ends and having oppositely connected therewith cranks 10 through clutches 11 operable by links 12 and a lever 14 so that both clutches may he released. or engaged simultaneously.

Connecting rods 15 of universal connection 16 with the wings B and pivotal ccnnections 17 with the cranks 10 so that when the engine is'in operation, and the clutches 11 engaged said wings Hop up and down somewhat in simulation to the movement, of a birds wings. A gondola or cabinet 18 is eX- tended from the forward portion of the body.

Each wing includes a plurality of blades or sections 2O hingedly mounted on cross bars 21 of hollow construction and having springs 22 anchored therein and engaged with the sleeve 23 of the blade which are circnmjacent the bars 20, to normally hold these blades upwardly but allowing them to swing down wardly when the wings are moved upwardly and then when the wings are moved downwardly the blades feather to a closed position. i

These blades are shown in side elevation in Figure 7 and incline upwardly and rearwardly so that as they flap down they tend not only to raise the airship but also to slide the same forwardly in the air and the descent and ascent ofthe machine may be controlled by the tail structure.

When gliding, of course, the clutches 11 may be disengaged and the wings will take the `position shown in Figure 2 automaticlutches maybe engaged and the flapping of the wings started.

It is thought that the construction, op

eration, utility and advantages of this invention will now be quite apparent to those skilled in this art without a more detailed description thereof.

rlhe present embodiment of the invention has been disclosed in considerable detail merely for the purposes of exemplification since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.

It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted' to without departing from the spirit or scope of the invention as hereinafter claimed 0r sacrificing any of its advantages.

Having thus described my invention, what I claim asnew is:

1. In an airship of the class described comprising a body of hollow construction adapted to be filled with lighter than air gas, a pairy of wings, one on each side thereof hingedly mounted thereto, each wing being formed with feathering blades, cross bars for supporting said blades, said cross bars being of elongated hollow tubular construction, said blades being formed with sleeves circumjacent said cross bars, and springs in the cross bars adapted for engagement with the sleeves of the respective blades for normally holding the blades in a raised closed position.

' 2. An airship of the class described comprising a body of hollow construction Y adapted to be filled with lighter than air blades pivotally mounted on the cross bars 'so Y for lmovementV between said bars, and springs arranged vwithin the said tubular cross bars, said springs adapted for engagement with the blades for normally holding the blades in a raised closed posi- 'tion for allowing the blades to swing downwardly when the wings are moved upwardly, said blades being ina normally closed position when said wings are moved downwardly.

3. An airshipof the class described comprising., a` body of, hollow construction v.adapted to be filled with lighter than air gas, said bodyrbeing constructed in simulation tothe body o f a bird, a'pair of wings fon each side of the' bodyphingedly mounted to said body, said wings having their outline in` simulation tobirdwings, a cradle "suspended from the body, a cabin structure Vprojecting forwardly from vsaid body, an enginein the cradle having a power shaft ex- 'tending to each side' of the body, cranks operatively connected with the shaft, connecting rods. operatively connecting the cranks withvthe wings, clutches interposed within the cranks from the shaft, each of ture.
